Method and apparatus for separating air and oil

Abstract

A method and apparatus for eliminating oil residue emitted from an engine used for powering motor vehicles, especially motorcycles, which includes a lower chamber separated by a plate having a plurality of openings and having at least one window located near a bottom of the lower chamber, an upper chamber having at least one slot, and a flexible membrane separating the upper and lower chambers. The apparatus may also include a gasket positioned beneath the lower chamber and a lid positioned over the upper chamber.

1 . A device for eliminating oil residue emitted from an engine comprising: 
 a gasket having at least one window; and    a vent body having a lower chamber and an upper chamber separated by a flexible membrane wherein the lower chamber includes at least one window near a bottom of the lower chamber and a plate having a plurality of openings therein and the upper chamber has at least one slot contained therein.    
   
   
       2 . The device of  claim 1  wherein the lower chamber is cylindrical.  
   
   
       3 . The device of  claim 1  wherein the upper chamber has a circumference that is greater than a circumference of the lower chamber.  
   
   
       4 . The device of  claim 1  wherein the vent body further comprises a stanchion.  
   
   
       5 . The device of  claim 1  further comprising a lid positioned over the vent body.  
   
   
       6 . The device of  claim 1  further comprising a snap ring positioned on top of the flexible membrane.  
   
   
       7 . The device of  claim 6  further comprising a washer positioned between the flexible membrane and the snap ring.  
   
   
       8 . The device of  claim 1  wherein the gasket includes two windows.  
   
   
       9 . The device of  claim 1  wherein the lower chamber of the vent body includes three windows.  
   
   
       10 . The device of  claim 1  wherein the flexible membrane is a rubber piston.  
   
   
       11 . A device for separating air and oil comprising: 
 a lower chamber separated by a plate having a plurality of openings therein and having at least one window near a bottom of the lower chamber;    an upper chamber having at least one slot; and    a flexible membrane separating the upper and lower chambers.    
   
   
       12 . The device of  claim 1  wherein the lower chamber is cylindrical in shape.  
   
   
       13 . The device of  claim 1  wherein the upper chamber has a circumference that is greater than a circumference of the lower chamber.  
   
   
       14 . The device of  claim 11  further comprising a gasket having at least one window, wherein the gasket is positioned beneath the lower chamber, and a lid positioned over the upper chamber.  
   
   
       15 . The device of  claim 11  further comprising a stanchion located below the lid and near the upper chamber.  
   
   
       16 . The device of  claim 11  further comprising a snap ring positioned on top of the flexible membrane.  
   
   
       17 . The device of  claim 16  further comprising a washer positioned between the flexible membrane and the snap ring.  
   
   
       18 . The device of  claim 11  wherein the lower chamber includes three windows.  
   
   
       19 . The device of  claim 11  wherein the upper chamber includes two slots.  
   
   
       20 . A method for making a device that eliminates oil residue emitted from an engine comprising the steps of: 
 providing a device having a lower chamber separated by a plate having a plurality of openings therein and at least one window near a bottom of the lower chamber, an upper chamber having at least one slot, and a flexible membrane separating the upper and lower chambers;    attaching the device to an engine in place of the engine's breather system; and    placing a lid over the device.
